Miley Cyrus has split from boyfriend Liam Hemsworth a week after her parents filed for divorce. Billy Ray Cyrus and his wife Tish officially announced their shock split last week and now it appears their 17-year-old daughter’s on/off romance with her Last Song co-star is over.

A source tells People.com that the pop star, who turns 18 on 23 November, split from Hemsworth, 20, before heading off on holiday with two girlfriends earlier this week.

The insider says, “Their on-and-off-again relationship is currently off. But you never know with Miley and Liam. They could be back on at some point.

“There was no drama. The relationship just ran its course. They were good friends first and remain friends.”

The couple split this summer after dating for a year, but reconciled in September.

Meanwhile, Cyrus’ brief vacation has already come to an end – she’s currently in Madrid, Spain preparing to perform at the MTV European Music Awards on Sunday.
